Abstract

L'invention concerne un panneau incurvé en matériau fibreux ondulé, comprenant deux feuilles de revêtement 56 et 56', et une feuille intermédiaire ondulée 58. Selon l'invention, la partie incurvée 60 du panneau est comprimée et a une épaisseur réduite par rapport à celle du restant du panneau. L'invention permet de former des panneaux comprenant des parties incurvees, ne comportant pas de plis sur leur face apparenteThe invention relates to a curved panel of corrugated fibrous material, comprising two cover sheets 56 and 56 ', and a corrugated intermediate sheet 58. According to the invention, the curved part 60 of the panel is compressed and has a reduced thickness compared to that of the rest of the panel. The invention makes it possible to form panels comprising curved parts, not including folds on their visible face.
